Wiring for Radio Faults
You may program the radio fault output (refer to the “Programming” paragraph in this
section) for either:
FAIL-SAFE Mode (UL requirement) LOW CURRENT Mode
Answer [Y] to “FLT REL ON (Y/N).” Answer [N] to “FLT REL ON (Y/N).”
Always energized [N.C.]. Normally de-energized [N.O.].
Will change state (and trigger a dialer, if
connected) in the event of power loss. Does not increase standby current.
Fail-safe mode increases the standby current
by about 10mA, which results in lower
battery backup time (about 15%) in the event
of power loss. NOT approved for UL installations.
Run two wires from the 7845CZ’s RAD FLT/ECP OUT and GND terminals to a zone on the
control panel. See Figure 8 for wiring the radio fault output.
NOTE: These connections may only be used for panels with common power supply and zone
grounds.
